Let My Colors Out deals with an issue that affects a lot of kids: a parent diagnosed with cancer. Emotions are represented by colors, scared (purple), sad and alone (blue), jealous of kids who aren't dealing with cancer in the family (green), pretending everything is OK and normal again (orange), angry (red), and happy despite all that is going on (yellow). The key message is that it's OK to feel whatever you're feeling, and the importance of letting those "colors" out.
